A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation. x + y = 24 3x + 5y = 100 What does the solution of this system indicate about the questions on the test? The test contains 4 three-point questions and 20 five-point questions. The test contains 10 three-point questions and 14 five-point questions. The test contains 14 three-point questions and 10 five-point questions. The test contains 20 three-point questions and 8 five-point questions.
Answer:
B, The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
x + y = 24
3x + 5y = 100
1. Rearrange the first equation to isolate either x or y.
x = -y + 24
2. Plug this new equation into the second equation to find the value of y.
3(-y + 24) + 5y = 100
-3y + 72 + 5y = 100
2y + 72 = 100
2y = 28
y = 14
3. Plug the value of y back into the other equation to find the value of x.
x = -14 + 24
x = 10
There are fourteen 5-point questions and ten 3-point questions.
Answer:
b) The test contains 10 three-point questions and 14 five-point questions.

Fraction =
Decimal =
Percent = %
Answer:
Fraction = 13/20
Decimal = 0.65
Percent = 65%
Step-by-step explanation:
Given:
13 out of 20 emails in mail inbox are junk emails
Solve for:
The experimental probability that next email is junk
Solution:
Step 1: Define the formula for calculating the probability
P = number of elements/total number of elements
Step 2: Perform the calculation
The number of elements (junk emails) = 13
The total number of elements (all emails) = 20
=> P(obtain odd number in experiment) in fraction form = 13/20
=> P(obtain odd number in experiment) in decimal from = 0.65
=> P(obtain odd number in experiment) in percent form = 0.65 x 100 = 65%

A circle with center (-1, 2) and radius of 8 has the equation
Answer:
c)
Step-by-step explanation:
The equation of the circle that has a center (-1, 2) and radius of 8 will be (x + 1)² + (y – 2)² = 64. Then the correct option is D.
What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at the (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x – h)² + (y – k)² = r²
A circle with center (-1, 2) and radius of 8.
Then the equation of the circle will be
(x – h)² + (y – k)² = r²
(x + 1)² + (y – 2)² = 8²
(x + 1)² + (y – 2)² = 64
Thus, the equation of the circle that has a center (-1, 2) and radius of 8 will be (x + 1)² + (y – 2)² = 64.
Then the correct option is D.

Answer:
For Sarah's dogs, we have:
Morning:
39, 21, 12, 27, 23, 19, 19, 31, 36, 25
if the ranges are:

B) 20 to 29: one of 21 pounds, one of 27, one of 23 and one of 25, so here we have 4 dogs.
C) 30 to 39. here we have the left 3 dogs.
then the table is:

A) Complete the table of values for y= x^2 - 4x
Answer:
y = x² - 4x
x = -1 y = 5
x = 0 y = 0
x = 1 y = -3
x = 2 y = - 4
x = 3 y = - 3
x = 4 y = 0
x = 5 y = 5
Hope this helps.
The equivalent values to complete the table are 5, -1, -4 and 0
Given the function according to the table shown:
[tex]y= x^2 - 4x[/tex]
When x = -1
[tex]y= (-1)^2 - 4(-1)\\y=1+4\\y=5[/tex]
When x = 1
[tex]y= (1)^2 - 4(1)\\y=1-4\\y=-3[/tex]
When x = 2
[tex]y= (2)^2 - 4(2)\\y=4-8\\y=-4[/tex]
when x = 4
[tex]y= (4)^2 - 4(4)\\y=16-16\\y=0[/tex]

The exponential function g, whose graph is given below, can be written as g(x)=a•b^x
Answer:
g(x) = [tex]8(\frac{1}{2})^x[/tex]
Step-by-step explanation:
Let the equation of the graphed exponential function is,
g(x) = [tex]a(b)^x[/tex]
Two points (0, 8) and (1, 2) lie on this graph.
For (0, 8),
g(0) = [tex]a(b)^0[/tex]
8 = a(1)
a = 8
For other point (1, 2),
g(1) = [tex]a(b)^1[/tex]
2 = ab
2 = 8b
b = [tex]\frac{2}{8}[/tex]
b = [tex]\frac{1}{4}[/tex]
Therefore, given exponential function wiil be,

The cost to.Purchase a tank.Of gasoline varies directly with the.Number of gallons purchased. You notice that the person in front of you spent $40.50 on 15 gals of gas. If your truck needs 26 gals of gas how much will you spend
Answer:
$70.20
Step-by-step explanation:
We need to first find the cost per gallon of the gas.
The person in front bought 15 gals at $40.50. The price of each gallon will therefore be:
40.50 / 15 = $2.70
You need to buy 26 gallons. The cost will be:
26 * 2.70 = $70.20
You will spend $70.20.

Answer:
10/9
Step-by-step explanation:
average rate of change in 0≤x≤9
=(3-(-7))/(9-0)=10/9
Answer:
The solution is 10/9
Step-by-step explanation:
Step 1: identify the right approach:
Given a function g(x) over a period of time, to find the average rate of change of g(x) over this period of time, we divide the change in g(x) by the change in x.
Step 2: Perform the calculation:
As shown in picture,
x = 0 => g(x) = -7
x = 9 => g(x) = 3
=> The change of x over interval [0, 9] is:
x_change = 9 - 0 = 9
=> The change of g(x) over interval [0, 9] is:
g(x)_change = 3 - (-7) = 10
=> The average rate (r) of change of g(x) over interval [0, 9] is:
r = g(x)_change/x_change = 10/9

There are two red jars of marbles and one blue jar of marbles. Jars of a certain color have the same number of marbles in them. There are 30 marbles in total. The difference between the number of marbles in a red jar and the number of marbles in a blue jar is 12. Find the number of marbles in each type of jar.
Answer:
There are 14 marbles in each red jar and 2 marbles in the blue jar
Step-by-step explanation:
There are two red jars of marbles and one blue jar of marbles.
Let the number of marbles in the red jar be x.
Let the number of marbles in the blue jar be y.
There are 30 marbles in total. This means that:
2x + y = 30 _____________ (1)
The difference between the number of marbles in a red jar and the number of marbles in a blue jar is 12. This means that:
x - y = 12 ______________(2)
We have a system of simultaneous equations:
2x + y = 30 _____________ (1)
x - y = 12 ______________(2)
Add them together:
3x = 42
=> x = 42/3= 14
Put the value of x in (2)
14 - y = 12
=> y = 14 - 12 = 2
Therefore, there are 14 marbles in each red jar and 2 marbles in the blue jar.

By completing the square
give answer correct to two decimal places.
( p.s the answer is not -5.32 or 1.32 )
Answer:
x = 1.32, -5.32
Step-by-step explanation:
x^2 + 4x - 7
Set equal to zero
x^2 + 4x - 7 =0
Add 7 to each side
x^2 + 4x =7
Take the coefficient of x and divide by 2
4/2
Square it
2^2 =4
Add to each side
x^2+4x+4 = 7+4
(x+2)^2 = 11
Take the square root of each side
x+2 = ±sqrt(11)
Subtract 2 from each side
x = -2 ±sqrt(11)
x=1.31662
x=-5.31662
To 2 decimal places
x = 1.32, -5.32

What change(s) should Sylvia make to the equation to find the value of t in the above scenario?
Answer:
Option (D).
Step-by-step explanation:
Initial population of the deer [tex]P_{0}[/tex] = 4800
Decrease in the population of the deer after every 8 years = [tex]\frac{1}{2}\times (\text{Initial population})[/tex]
Decrease in population is an exponential process, so the expression representing population will be,
[tex]P_{t}=P_{0}(1-r)^x[/tex]
Where [tex]P_{t}[/tex] is the population after 'x' slots of 8 years.
r = fraction of decrease in the population
x = [tex]\frac{\text{Number of years}}{8}[/tex]
By substituting the values of r and x in the expression,
[tex]P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}[/tex]
[tex]P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}[/tex]
Therefore, Sylvia should do few corrections in her expression.
(8) should be replaced by ([tex]\frac{1}{2}[/tex]) and [tex]\frac{t}{2}[/tex] should be replaced by [tex]\frac{t}{8}[/tex].
Option D. will be the answer.
